Further efforts are needed to achieve the climate protection targets. This was also the tenor of two events on Tuesday at the Berlin Energy Days: In a series of lectures by the Federal Ministry of Economics and Energy (BMWi), experts presented "Innovative solutions for existing buildings", and in the evening the Bergische Universität Wuppertal presented the international Solar Decathlon Europe 2021 competition. Student teams can apply here with ideas that, among other things, aim at a resource-efficient and climate-neutral city.

The topic "Energy Sprong" was the central theme of the lectures and discussions at the BMWi's morning event. With this principle, also known as "serial refurbishment", architects and building planners rely on digitised, standardised processes. Prefabricated construction and technical elements are used on the construction site. It is a holistic concept that includes both façade elements and building services.

Dr. Alexander Renner, head of department "Energy policy issues of principle in the building sector" at the BMWi, stressed in his lecture that conventional solutions alone would not be sufficient to increase the current renovation rate from 1% to the required at least 2%.
